Our Digital Substation Solutions
IEC61850-Compliant Industrial Networking
IEC61850 is the international standard governing communication within digital substations. Its GOOSE (Generic Object Oriented Substation Event) messaging protocol enables protection functions with millisecond-level response times — making network performance not just an operational consideration but a safety-critical one.
LHS supplies and configures IEC61850-compliant industrial switches and networking equipment tested for reliable operation in substation environments.
Power SCADA Connectivity & Integration
Power SCADA systems rely on a reliable, low-latency network to communicate between field devices, remote terminal units (RTUs), and the control center. Our industrial networking solutions provide the deterministic, redundant communication fabric that Power SCADA systems require — supporting both legacy serial protocols and modern IEC61850-based architectures.

Time Synchronization & GPS/PTP Networks
Precise time synchronization is fundamental to digital substation protection and fault recording. Our solutions support IEEE 1588 Precision Time Protocol (PTP) for sub-microsecond synchronisation across the substation network — essential for distance protection functions and sequence-of-events recording.
Cybersecure Substation Networks
As substations become digitally connected, cybersecurity becomes a mission-critical consideration. Our industrial networking solutions incorporate VLAN segmentation, port security, and network access control features aligned with IEC 62351 security guidelines for power systems communication.
Use Cases
Digital substations are the foundation of tomorrow’s resilient and intelligent power grids. Our ruggedized networking solutions ensure real-time performance, seamless interoperability, and mission-critical reliability across diverse substation applications:
- Digital Substation Automation (IEC 61850)
- Power SCADA Redundant Backbone
- PTP Clock Synchronization
- Fire Command & Control Center (FCC) & Field Protocol Gateways

Why Singapore’s Grid Modernization Demands Digital Substation Infrastructure
Singapore’s EMA has set ambitious targets for grid digitalisation as part of the Singapore Green Plan 2030 and the broader Smart Nation initiative. The integration of rooftop solar, vehicle-to-grid charging infrastructure, and advanced demand response programmes all depend on the real-time data exchange that only digital substation architectures can provide.
For project developers, EPCs, and utilities operating in Singapore’s power sector, specifying IEC61850-compliant networking from the outset is increasingly a regulatory expectation rather than a design choice.
Dong Nai Power Grid, Vietnam IEC 61850 Network
Using Kyland’s SICOM3024P, Dong Nai’s substations achieved packet loss-free communication under high humidity. IEC 61850 GOOSE messaging and GPS PTP were implemented for reliable automation.

Frequently Asked Questions
1. What is a digital substation and how does it differ from a conventional substation?
A conventional substation uses hardwired copper connections between protection relays and control systems. A digital substation replaces these with a standardized Ethernet network governed by IEC61850, enabling faster communication, easier configuration, and real-time integration with SCADA systems. Digital substations also reduce copper cabling significantly, lowering both installation costs and maintenance complexity.
2. What does IEC61850 compliance mean for substation networking?
IEC61850 is the international standard for communication in electrical substations. Compliance means that the networking equipment meets the specific performance, timing, and reliability requirements defined in the standard — including support for GOOSE messaging, sampled values, and MMS (Manufacturing Message Specification) protocols used in substation automation.
3. What is Power SCADA and how does it connect to substation networks?
Power SCADA (Supervisory Control and Data Acquisition) is the system used by grid operators to monitor and control the power network. It connects to field devices — protection relays, meters, circuit breakers — via the substation communication network. A properly designed digital substation network provides the low-latency, redundant communication that Power SCADA systems require for reliable operation.
4. Can LHS support both new-build and substation retrofit projects?
Yes. LHS works with project developers, EPCs, and utilities on both greenfield digital substation builds and the retrofit of legacy substations to IEC61850-compliant architectures. We provide product supply, system design support, and configuration services.
